To all whom it may concern: I Be it known that I, EDWARD G. Bonn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have i invented certain new and useful Improvements in l Cushions, (Case B), of which the following is a specifica- I l This invention relates to cushions and more particularly to that class employed as seat cushions for seats of the type commonly used in cars.

The object of the invention is to effect certain improvements in cushions of this type whereby maximum strength is obtained, and moreover, a simple and inexpensive construction is provided. I

In accordance with my invention I construct a cushwhich may be pressed to the desired form at relatively small expense;

ion having a frame formed of sheet-metal frame sections extending across between opposite members of this frame are a plurality of transverse rails 2 0' or slats which serve to prevent the distortion of the cushion frame andalso support the springs which yieldingly i position the covering material of the cushion. These l transverse slats are peculiarly formed to give greater I strength and in order thatthey will better withstand the strain towhich they are subjected. At the ends of the frame I provide rocker plates which co-act with the rockers ordinarily employed in car seats to support the cushion and these rocker plates may be so formed that they also serve as slats at the ends of the cushion for I supporting sets of springs. In order that these rocker plates may be more firmly secured to the frame of the cushion I provide them with integral portions which may be secured to the end members of the cushion frame, and these end portions are shaped so that they do not in any way interfere with the flanges provided at the lower edges of the end members of the frame to which the covering material of the cushion is secured.

I have illustrated the preferred embodiment of my invention in the accompanying drawings, in which Figure 1 is a top view 'of one end of the cushion with the covering removed, Fig. 2 is a section of the same, Fig. 3 is a top view of one of the rocker plates, Fig. 4 is a side view of the same, Fig. 5 is a section on line 5-5 of Fig. 3, Fig. 6 is a side view of one of the transverse slats, I Fig. 7 is a top view of the same, and Fig. 8 is a section on line 88 of Fig. 6.

Referring to these drawings, the frame of the cushion is of rectangular shape and consists of a plurality of frame sections secured together at their ends in any 1 suitable manner as by mitering the ends and riveting right angle braces thereto. Both the side members 1 and the end members 2 of the frame are preferably formed of sheet-metal, pressed to the desired form. Their cross-sectional shape may be that shown in Fig. 2, that is, they may have a body portion 3 and inwardly rocker portion 20 connected to extending flanges 4 and 5 at the lower and upper edges respectively. The flange 4 may be curled at its end to facilitate attaching the covering material thereto, and the upper flanges 5, may also be curved to give a rounded upper edge to the cushion.

Extending across between the side members 1 and the frame are a plurality of transverse rails or slats 6, secured at their ends to the side members 1, and each of these slats is arranged to carry a series of spiral springs 7, which at their upper ends support flat springs 8, extending across the cushion and secured at their ends by rivets 9 to the side members 1. The covering material, not shown in the drawings, is drawn tightly over these flat springs 8 and secured to the flanges 4 in any suitable manner. Each of the slats 6 is provided with a lengthwise corrugation 10, as shown in Figs. 6, 7 and 8, which serves to stiffen the slat, and each slat has integral angular feet 11, preferably bent at right angles to the body portion of the slat and provided with openings 12 for the reception of rivets by which the feet are secured to the side members 1- of the frame intermediate the flanges thereof. securely relatively to the body portion of the slats 6, side flanges 13 are formed integral with the body portions of the slats and the feet thereof, the ends of these side flanges 13 extending beyond the ends of the corrugations 10 so that the slats are stiffened throughout their length and bending thereof except under unusual strain is prevented.

At'the ends of the frame are rocker plates provided with openings to receive the dowel pins ordinarily provided on the rockers of car seats. These rocker plates are so formed that they not only serve to support the cushion upon the rockers but also support a series of springs so that the employment of slats at the ends of the frame is avoided. The construction of the rocker plates is best shown in Figs. 3, 4 and 5, from which it will be seen that each plate 14 is formed from a stamping of sheet-metal, pressed to the desired shape. Each of the plates has an integral slat portion 15 provided with a lengthwise corrugation 16 and integral angular feet 17 having openings 18 therein by which connection to the frame members 1 is effected. The feet 17 are sustained in position by gussets 19. Adjacent to and integral with the slat-portion 15 is a the slat portion 15 by a web 2. so that the rocker portion 20will be at a lower level than the slat portion 15, and this rocker portion has openings 22 therein for the dowel pins of the rocker. On the other side of the rocker portion 20 is an integral extension which is adapted to be secured to the end member 2 of the cushion frame to support the rocker plate thereon, but in order to leave aplearance around the flange 4 of the end member, this In order to hold the angular feet 11 more said frame, said slats having angular feet at the ends extension is bent in such a way as to leave free space between it and flange 4. This will be best. understood from Fig. 5, which shows the extension as consisting of a portion 23, bent at right angles to the rocker portion 20, strengthening gussets 24 being provided to stiffen the construction, a portion 25, extending in a plane parallel to the rocker portion 20 and a downwardly turned flange 26 at the end of the portion 25,

The rocker plate is secured in position at the end of the frame, as shown in Fig/l, and is supported both by the side members of. the frame and the end member and when thus held in position the springs 7 are mounted on the slat portion of the rocker plate.

It will be seen more particularly from Fig. 5 that the construction of the rocker is such that while it is supported by the end member of the frame, an ample clearance is provided around the flange 1 of the end member so that the covering material of. the cushion can be readily draw'n over this flange and secured thereto.

Having described my invention, what I claim as newand desire to secure by Letters Patent is:
